Is there a list of non-unique vessels that are explicitly used by generic pirates? Obviously nearly anything that isn't unique or so small a run to leave all examples accounted for could wind up in pirate hands, but I'm looking for stuff that explicitly gets used.

What I could find

Sub Colossal:

CloakShape Fighter

I4 Ionizer Starfighter*

All uglies

Edit: T-Wing Interceptor

Colossal:

Citadel-Class Cruiser

Corellian YT-1250 Freighter

Penumbra-Class Attack Shuttle

Corellian YV-545 Light Freighter

Colossal (Frigate) or larger:

CR90 Corellian Corvette

Penumbra-Class Attack Shuttle

Mobquet Medium Transport

Gladiator-Class Star Destroyer*

Baas-Class Space Station*

Marauder Corvette*

Consular-Class Cruiser*

*explicitly second hand
